我院和鞍山整流器厂组成的变频调速科研组在鞍山市科委和冶金部科技司的支持下,于1983～1984两年间研制了《可控低环流余弦交截交——交变频装置》和《微机控制规则采样交——交变频装置》并于1984年12月通过了鞍山市科委的技术鉴定,与会专家认为上述成果处于国内领先地位,填补了国内空白。两名82届研究生的课题“笼形感应电动机转矩传递函数常数化控制系统”和“绕线式感应电动机双馈变频调速系统”就是利用前者做变频器组成的,已在实验室运转并做了一些理论分析和实验研究工作。两名83届研究生除继续双馈变频 Our institute and Anshan Rectifier Factory composed of frequency control scientific research group in Anshan City Science and Technology Commission and the Ministry of Science and Technology, Ministry of Metallurgical support, in 1983 ~ 1984 two years developed a “controllable low-flux cosine cross-cut AC-AC frequency device” And “Microcomputer Control Rules Sampling - AC Frequency Conversion Device”. In December 1984, it passed the technical appraisal of Anshan Municipal Science and Technology Commission. The experts attending the seminar said that the above achievements are in a leading position in China and filled the gap in China. Two 82 graduate students subject “Cage induction motor torque transfer function constant control system” and “Wound induction motor doubly-fed inverter speed control system” is the use of the former inverter, has been in the laboratory and Made some theoretical analysis and experimental research. In addition to two 83-year graduate students continue to double-fed inverter
